How Lutherans define God--from the Augsburg Confession (1530)

"Our Churches, with common consent, do teach that the decree of the Council of Nicaea concerning the Unity of the Divine Essence and concerning the Three Persons, is true and to be believed without any doubting; that is to say, there is one Divine Essence which is called and which is God: eternal, without body, without parts, of infinite power, wisdom, and goodness, the Maker and Preserver of all things, visible and invisible; and yet there are three Persons, of the same essence and power, who also are coeternal, the Father, the Son, and the Holy Ghost. And the term "person" they use as the Fathers have used it, to signify, not a part or quality in another, but that which subsists of itself.

They condemn all heresies which have sprung up against this article, as the Manichaeans, who assumed two principles, one Good and the other Evil: also the Valentinians, Arians, Eunomians (extreme Arians), Mohammedans (Muslims), and all such. They condemn also the Samosatenes, old and new, who, contending that there is but one Person, sophistically and impiously argue that the Word and the Holy Ghost are not distinct Persons, but that "Word" signifies a spoken word, and "Spirit" signifies motion created in things." Book of Concord, (1959, translated from German)

The Roman Catholic Church and all orthodox groups of Christians accept this without qualification, although if you really investigate today's seminaries, the teaching of Jesus as a separate created being lingers in academe and there are priests and pastors alike who are playing word games, speaking with forked tongues and crossed fingers.

The Augsburg Confession's teaching of the Trinity has been held throughout all the generations of the Church. But after this point, Christians start to diverge. And if there is a sect today that gains popularity and is considered heretical by other Christians, this statement is usually the problem.

There's a reason the church needs creeds and confessions; error and heresies just keep repeating themselves in each generation. Arianism, whether lite or extreme, is an attack on the diety of Christ, and that along with Gnosticism (attack on his humanity) seem to be at the root of most of today's false teachings. Either way--whether you're marketing the church's message of good works and personal growth ala Rick Warren type stuff never mentioning the saving work of Christ or you're caught up in DiVinci Code type speculation and titillation, you're just repeating the old problems foretold in the New Testament, particularly Jude. The early church fathers had today's emergent/emerging church trends in their sites.

Although Lutherans and Catholics link arms in many areas of politics, social justice, abortion, euthanasia, prison ministry, health issues, disaster relief and care of the poor and homeless, they are as divided today as they were in the 16th century on doctine--grace, faith, justification, the role of (Peter) tradition in the church, the sacraments, indulgences, purgatory, and the role of the priesthood.
